In this paper, the marine soft soil is mixed with 10% cement added with 0.5% NaOH and 0.5% Na2CO3 separately, which form two types of new cement-soils. Comparing with the undisturbed soil and the 20% cement-soil results in that the alkalescence additive can contribute to generate a large number of needle-like, rod-like or fibriform hydrate calcium silicate crystals. The hydrate calcium silicate crystals can inhibit the generation of calcic alum crystal which would bring expansive action. At the mean time, it can separate out hydrate calcium. The hydrate calcium silicate crystals and hydrate calcium constitute the filling and inclusions together among soil particles and on the surface of soil particles, which cut down the interstices of cement soil obviously. Therefore, the soil mass can be reinforced and the intensity can be improved.

Degradation test in vitro was carried out in phosphate buffer solution (0.1M, pH7. 4) at 37 ℃. The buffer solution was changed daily. Degradation test in vivo was implanted the sample to subdermal in adult ICH rat in the scapular area lateral to the dorsal midline. At suitable time the samples were recovered. Molecular weight changes in surface layer and bulk of polymer sample were measured by GPC and weight loss was determined gravimetrically. It was found that the degradation behavior can be regulated by changing the composition of copolymers. The critical compositions from surface to bulk degradation behavior for PGCA, PLCA, PLMCA, PLDCA systems were 15-20, 20-30, 30- 40, 40 of mol percent GA or LA unit in copolymers, respectively. The degradation behavior of PGCA, PLCA, PLMCA, PLDCA systems were compared and analysed. Some factors influencing the degradation character, such as copolymer composition, hydrophobicity, crystallinity and enzyme affect etc. played important role.

This paperindicated that it was good for condensation reaction when benzene-ring bearingelectron-attaching groups. It also showed that and the 6-hydroxyl group could bereacted with acyl halide, haloid ether and halo alkene, but not with halo alkane. It wasnot only the first time to find that the reaction product of D-mannitol and aromaticaldehyde is tri-condensation derivatives, but also the first time to obtain thep-phthaldehyde-sorbitol derivatives containing eight hydroxyl groups.

Conbining previous results with our results, we conclude that the soluble gp130 mutant containing CBD can antagonize the biological activities of IL-6 by competitively binding IL-6/IL-6Rα with wild-type gp130, and the membraneanchored mutant could transduce IL-6 signal, but its efficiancy was much lower than that of wild-type gp130, therefore, we thought the Ig-like module also played an important role in IL-6 signal transduction by involving in the formation of a hexameric IL-6 receptor complex.
结合以前的研究结果,我们认为只含胞外CBD区的gp130突变体通过与膜结合型gp130竟争结合IL-6/IL-6Rα复合物而具有拮抗IL-6功能的作用;而只含胞外CBD区的gp130突变体,尽管仍能传导IL-6信号,但其效率远低于野生型gp130,因此,我们认为gp130的Ig样区在IL-6转导中也起着十分重要的作用。

Characteristics of Inclusions: After the tea is kept for a long period of time in a stall and deep fermentation processing begins, the specialties of material and manufacturing make many bioreactions occur for thorough activation of microbes to excrete extra-cellular enzymes, which impacts over 500 stuffs of tea. Theses microbes contain catechin, polyphenols, amylase, cellulose, protein, lipid ,alcohol, ketone, vitamin, microorganism, and organic acid, making them transform, isomerize and degrade, polymerize and couple, so as to produce amylase, thearubigins, theaflavins, cellulose, and microelements that other commercial teas could not produce or produce too little.
